The "Good Hair Study” asked 4,000 participants to take an implicit association test showing black women with both natural and smooth hair. Most – across race and gender lines – had bias based on the texture of black women’s hair with more white women finding natural hair less “beautiful” and “professional.” However, based on other parts of their study, the researchers concluded that the bias is learned, not innate, so it can be unlearned. Younger people were more accepting of natural hair as were white women who had more exposure to black women’s natural hair.
